Question

尝试创建一个存储方法的字典，这些方法在Windows窗体中创建东西等等。

该方法不带参数，并返回所有已创建项目的字典。

Dictionary<string, Func<Dictionary<string, dynamic>>> games = new 
Dictionary<string, Func<Dictionary<string, dynamic>>>()
{
    { "Buttoncatch", //I dont know what to write here
        {
           var objects = new Dictionary<string, dynamic>
           return objects;
        }
    }
};

我不想这样做：

public Dictionary<string, dynamic> Buttoncatch()
{

}
games["Buttoncatch"] = Buttoncatch //dont even know what to write here,

为什么字典dynamic的值类型可以是Func<Dictionary<string,dynamic>>。

这些方法可以创建为普通的lambdas：

Dictionary<string, Func<Dictionary<string,dynamic>>> games = new     
Dictionary<string, Func<Dictionary<string, dynamic>>>
{
   {"Buttoncatch", 
    () => {
             var objects = new Dictionary<string, dynamic>
             return objects;
          }
   }
};

当你以这种方式声明字典时，行

games["Buttoncatch"] = Buttoncatch;

也会奏效。
